I imagine the red line indicates the expected destination and the blue line was soooo close until it got confused and took a stroll over to Columbus.

I’ve seen some bad ones lately too. Had a package go from Texas to Florida, to Chicago, to the northeast somewhere and finally back to Florida for delivery. And a few where clearly something has glitched in the tracking system, leaving locations before they arrived at them, being picked up from one place but shipped from the other side of the country, etc.
